The L-IP Routers LIP‑1ECTC, LIP‑3ECTC, LIP‑33ECTC, and LIP‑3333ECTC connect twisted pair channels (TP/‌FT‑10 or TP/‌XF‑1250) with the Ethernet/‌IP channel (IP‑852) in LonMark Systems. L-IP routes CEA‑709 packets through an IP based network such as a LAN (Ethernet), an Intranet, or even the Internet.

In order to provide optimal router configurations, the L-IP is available in four different versions providing either 4 x TP/ FT‑10, 2 x TP/ FT‑10, 1 x TP/FT10, or 1 x TP/ XF‑1250. Every L-IP supports the operating modes “Smart Switch Mode” and “Configured Router Mode”.

For an easy integration on the IP side, the L-IP provides a Web interface. On L-IP Routers LIP‑1ECTC, LIP‑3ECTC, LIP‑33ECTC, and LIP‑3333ECTC the Web interface can also be used via an encrypted HTTPS connection. Through this Web interface, the built-in CEA-852 Configuration Server can be switched on and configured. The Configuraton server is thus always available online in the network and no additional software tool is required.

Besides the router functionality, the L-IP Routers provide outstanding capabilities for network diagnostic and analysis. They allow the LPA (LOYTEC Protocol Analyzer) transparent access to the twisted pair channels (TP/‌FT-10 or TP/XF-1250) on the device via Ethernet/‌IP – via a local Intranet or the Internet. This allows a fast analysis of data communication and reduces time-consuming troubleshooting. All system registers are available as OPC XML‑DA and OPC UA data points.

The L-IP Routers LIP‑1ECTC, LIP‑3ECTC, LIP‑33ECTC, and LIP‑3333ECTC are equipped with two Ethernet ports. It can either be configured to use the internal switch to interconnect the two ports or every port is configured to work in a separate IP network.

When the Ethernet ports are configured for two separate IP networks, one port can be connected for instance to a WAN (Wide Area Network) with enabled network security (HTTPS) while the second port can be configure to be connected to an insecure network (building LAN) where the standard building automation protocols are present (e.g. IP-852). These devices also feature firewall functionality of course to isolate particular protocols or services between the ports.

Using the internal switch, a daisy chained line topology of up to 20 devices can be built, which reduces costs for network installation. The IP switch also allow the setup of a redundant Ethernet installation (ring topology), which increases reliability. The redundant Ethernet topology is enabled by the Rapid Spanning Tree Protocol (RSTP), which is supported by most managed switches.
